Willmovetosuperview in iOS: Methods

Look directly at the code:

#import "CMoveView.h"

@interface Cmoveview ()

Record Last parent view

@property (nonatomic, strong) uiview* Oldsuperview;

@end

@implementation Cmoveview

It is possible to use this method when you rewrite a uiview, and the system automatically executes this method when the view's parent class changes. Newsuperview is the new parent view of this view. Newsuperview may be nil.

-(void) Willmovetosuperview: (UIView *) Newsuperview {

[Super Willmovetosuperview:newsuperview];

NSLog (@ "oldsuperview=%@,newsuperview=%@", Self.oldsuperview,newsuperview);

Self.oldsuperview = Newsuperview;

NSLog (@ "%s", __func__);

}

@end
